Can someone explain to me how I convert a 32-bit floating point value to a 16-bit floating point value?

(s = sign e = exponent and m = mantissa)

If 32-bit float is 1s7e24m
And 16-bit float is 1s5e10m

Then is it as simple as doing?

int     fltInt32;
short   fltInt16;
memcpy( &fltInt32, &flt, sizeof( float ) );

fltInt16 = (fltInt32 & 0x00FFFFFF) >> 14;
fltInt16 |= ((fltInt32 & 0x7f000000) >> 26) << 10;
fltInt16 |= ((fltInt32 & 0x80000000) >> 16);

I'm assuming it ISN'T that simple ... so can anyone tell me what you DO need to do?
